Polyvinylidene Fluoride (PVDF) Syringe Filters - SPEC18225

Compact laboratory spaces with highly turbid sample processing requirements face challenges when standard prefiltration options consume excessive bench area while still demanding sterile integrity for contamination-sensitive workflows. Sterile 3.0µm PVDF membrane technology delivers space-efficient coarse prefiltration with exceptional chemical resistance and ready-to-use gamma-irradiated integrity. Hydrophobic construction in 20mm ABS housing with threaded double luer lock provides contamination-free coarse particle removal for pharmaceutical formulations, biological samples, and chemical processing where compact design and broad solvent compatibility both matter.

Key PVDF Membrane Characteristics

• Hydrophobic surface requires alcohol pre-wetting before aqueous processing, activating the membrane for consistent flow and preventing channeling during sample filtration
• Outstanding chemical stability withstands acetonitrile, methanol, chlorinated solvents, and aggressive organic reagents that rapidly degrade cellulosic and polyamide membrane alternatives
• 3.0µm pore size provides coarse prefiltration for heavily particulate samples, removing large debris that would rapidly clog finer membranes in your multi-stage workflows
• Ultra-low protein binding maintains biomolecule concentrations during coarse prefiltration, preventing adsorptive losses that compromise recovery in your biological sample preparation protocols
• Temperature tolerance to 80°C supports elevated-temperature sample processing while maintaining chemical compatibility across diverse pharmaceutical and chemical laboratory applications

Key Construction Characteristics

• ABS housing delivers chemical resistance to common organic solvents while providing mechanical durability for manual filtration operations in routine sample preparation
• Threaded double luer lock connection ensures secure, leak-proof attachment to syringes and tubing systems, preventing sample loss during processing workflows
• 72.5psi maximum operating pressure supports manual syringe filtration and integration with low-pressure pumping systems for continuous sample preparation
• Sterile gamma-irradiated packaging provides contamination-free prefiltration without requiring autoclave sterilization, streamlining workflows in pharmaceutical and biotechnology cleanroom environments

Designed for your space-constrained workflows where heavily turbid samples require sterile coarse prefiltration without consuming excessive bench area. PVDF's chemical versatility handles the challenging matrices your laboratory processes. Sterile individually-wrapped units maintain your contamination control protocols while delivering the solvent resistance and prefiltration capacity that protect downstream equipment, extend fine filter life, and ensure consistent sample preparation across demanding pharmaceutical, biotechnology, and chemical applications where compact sterile prefiltration determines operational success.
